Accurate and tunable: The title compounds can detect reactive oxygen species (ROS) in cell culture, tissue explants, and for the first time in vivo. The hydrocyanines are synthesized by reduction of the cyanine dyes with NaBH4. They can accurately detect nanomolar levels of ROS, have excellent stability against autoxidation, and have tunable emission wavelengths in the range 560–830 nm.
准确且可调:标题化合物可以检测细胞培养物、组织外植体中的活性氧 (ROS),这是首次在体内检测。氢花青是通过用 NaBH 4还原花青染料来合成的。它们可以准确检测纳摩尔水平的 ROS,对自氧化具有出色的稳定性,并且具有 560-830 nm 范围内的可调发射波长。
